SAFETY-GATE.

SPECIFICATION forming part of Letters Patent No. 345,587, dated July 13,1886.

Application filed November 3, 1885.

To @ZZ whom it may concern:

Be it known that l, VILLIAM HANLEY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvementsin Safety-Gates; and Ihereby declare the following to be a full, clear, and exact descriptionof the same.

My invention relates to a device for the foregoing purpose, in which thebarrier is formed of a continuous cable extending from one post to theother on the same side of a railroadtrack, and capable of being raisedinavertical direction to remove the barrier.

It is my object t0 provide a simple and effective mechanism for raisingand lowering the cable barrier; and to this end my invention consists inthe general construction of the mechanism I have provided for thepurpose.

My invent-ion further consists in certain details of construction andcombinations of parts, all as hereinafter more fully set forth.

Referring to the drawings, Figure l represents my improved gate inelevation, showing also means for actuating the cable barrier; Fig. 2, abroken plan View of the gate portion of the device, showing the mannerof arranging the various ropes or cables on the upper pulleys or drums.;and Fig. 3, a sectional view through a portion of one post, showing theconstruction of the gong mechanism and of the means for actuating thesame automatically.

A A are the posts, to be located on opposite sides of arailroad-crossing in line with the track, and of a height at least topermit thecable barrier, hereinafter described, to be raised thedistance required by municipal regulation. Toward the upper extremity ofeach post a pulley, B, or, more accurately stated, a drum is journaled,having a diameter of suiicient extent to provide great leverage, and toafford a circumference which will permit the cable barrier to be raisedto its full height vwith but few revolutions.

C C are pulleys unlike the pulleys B, inasmuch as they are not drums,but simple pulleys journaled below the latter on the posts at thedistance above the ground at which it is desired to provide the barrier;and the pulleys C are vertically adjustable by having theirjournal-bearings r (see Fig. 3) securedV upon serial No. 181,738. (Nomodel.)

plates q, provided with slots p, and secured to the posts by means ofset-screws o, inserted through the slots.

The pulleys B are connected together by means of a rope or cable, D,wound around each at least twice, as represented in Fig. 2, to preventslipping, and crossed. An endless cable or rope, E, is wound around eachpulley B, also at least twice, and connects the latter with the pulley Cdirectly below it by being passed around the same; and any slack in thecables E is taken up by adjusting the pulleys C accordingly, it beingimportant that the endless cables shall always be maintained taut. Acable, F, in the form of a rope orsin gle wire, is attached at itsopposite ends to the inner strands of the endless cables E at pointsequidistant and the desired height above the ground, and affords, whenoccupying such position, the barrier, a suitable signal .for theday-time being provided in the form of fabric, n, or other suitablematerial of a desired color, attached to the barrier, as shown, andstretched, to prevent its being 'wrapped or wound around the same by thewind or by other causes, by means of strings m, secured to its freecorners and to the endless cables E.

To operate my device to raise or lower the barrierit is only necessaryto pull on one or the other strand of an endless cable E; and when thebarrier has been raised in this inanner it may be fastened to preventits unintentional descentl by slippinga loop, Z, provided for thepurpose, over a hook or projection, l', on a post.'Y On one of the postsA (or on both, if desi red,though the provision on one is thoughtsuflicient) a gong, G, is secured by passing its hollow rod k throughthe post and screwing it into an opening provided in the plate q, andthe hammer G is bent, as shown, and fulcrumed to the stem, and pivotallyconnected at one end to a rod, H, extending through the hollow stem 7c,and provided with with a knob, t', affording a bearing to be struck bycams h on the pulley C, which operate in the rotation of the pulley at aright angle to the rod H, to force the latterinward and sound the gongonce for each cam.

Ordinarily the barrier will be operated at a post A in the mannerdescribed; but when it is desired or necessary to operate it from adistance, this may be done by means of arope IOO - be provided to effectthe operation.

Two gates, like the one hereiubefore de scribed, are generally providedfor a railroadcrossing; but no particular mechanism is shown in thepresent connection for operating them simultaneously or separately, forthe reason that the purpose will suggest suitable means to any mechanic,a pulley-connection with eable affording an appropriate eontrivauce.

Vhat I claim as new, and desire to secure by Letters Patent, is-

k1. A safety-gate having posts A on opposite sides of a crossing, andcarryingpulleys B and C toward their opposite extremities, endlesscables E, connecting the pulleys B and C on each post, a cable, D,crossed, and connecting pulleys B on opposite posts, and a cable, l",secured at opposite ends to the inner Strands of the endless cables E,and affording a barrier when lowered, the parts being combinedsubstantially as described.

2. A safety-gate having posts A on opposite sides of a crossing, andcarrying pulleys B and pulleys C toward their opposite extremities,endless cables E, connecting the pulleys B and C on cach post, a loop,Z, on an endless cable E, to engage with a projection, Z', on theadjacent post, a cable, D, crossed, and connecting pulleys B on oppositeposts, and a cable, F, secured at opposite euds to the inner strands ofthe endless cables E, and affording a barrier when lowered, the partsbeing combined sub-` stantially as described.

3. A safety-gate having posts A on opposite sides of aerossing, andcarrying pulleys B and pulleys C toward their opposite extremities,

endless cables E, connecting the pulleys B and C on each post, a loop,l, on an endless cable E, to engage with a projection, Z', on theadjacent post, a cable, D, crossed and connecting pulleys D 011 oppositeposts, and a cable, F, secured at opposite ends to the inner strands ofthe endless cables E, and provided with a signal, n, secured at itsopposite ends to the at opposite ends to the inner strands of theendless cable E, and affording a barrier when lowered, and an adjustablegong, G, upon one post, having its hammer vibrated by the cams on theadjacent pulley C in its rotatiointhe parts being combined and arrangedto operate substantially as described.
